Clogged or dirty air filters
The easiest problem to prevent and one of the most common. A clogged filter chokes airflow, which strains the blower and can freeze the indoor coil.

Examples of our work
What we fix most in San Bernardino homes
Refrigerant leaks
Cooling fades, air feels cool instead of cold, and ice may show on the lines. The leak has to be found and fixed, since topping off alone is a short term patch.
Capacitor and electrical failures
Long summer run times and heat wear out capacitors and contactors. The outdoor unit hums, the fan will not turn, or the system trips the breaker.
Undersized or leaky ductwork
Many older homes have ducts that leak or were sized for a smaller system. The AC runs hard while some rooms never cool.
Frozen evaporator coils
Usually low airflow or low refrigerant. Turn cooling off, run the fan to thaw it and call.
Why the Inland Empire is hard on equipment
San Bernardino summers are hot and dry, the AC runs for months, and dust, along with smoke from regional wildfires on bad days (see AirNow), clogs filters and coats outdoor coils.
A dirty coil and a starved blower are behind a large share of the breakdowns we see. Older housing adds ducts that leak into hot attics.
Rialto and Fontana, just west of San Bernardino, face the same climate, and we serve both.
A seasonal checklist that prevents breakdowns
These steps are what a good spring tune up covers. Some you can do yourself, and some are for a technician:
Safe for you to do
- Change the air filter on schedule and check it monthly in summer
- Clear leaves and debris from the outdoor condenser
- Check the thermostat settings and batteries
- Look over any exposed ductwork for gaps or damage
Best left to a technician
- Test refrigerant levels
- Flush the condensate drain line
- Straighten bent condenser fins
- Test capacitors and electrical connections
What happens on a repair visit
- You tell us what the system is doing. When it stopped, what you hear.
- We check the basics. Thermostat, filter, breaker and airflow.
- We test and measure. Electrical parts, refrigerant pressures, temperature drop across the coil, and the motors, with a look at the outdoor coil and the drain.
- You get the options and the price. Before work begins, with a replacement price too if the system is old and the repair is large.
- We repair and test it. We confirm it is cooling before we leave.
Repair or replace?
We look at the age, what failed, repair history and the ducts. If a system is 10 to 15 years old and needs a compressor or coil, replacement usually makes sense.
A young system with a failed capacitor does not. See AC installation in San Bernardino.
